Love a good cargo bike!
Is that a fixie, “just” a single speed, or can it be set up either way? Regardless, my hat’s off to you - I don’t think my knees could take a single speed all the time.
I can’t speak to your ride, but I have no hesitation riding my ebike in the rain. I’ve got a Shimano mid drive designed for EMTBs, if it can handle muddy MTB trails a little rain isn’t going to hurt it
Yes, but also no - if an ebike is replacing a car trip, it’s using 2 orders of magnitude less resources. As an example, this morning I had to take my kiddo to her summer camp, and it’s about 5 miles one way. I’m relatively fit, but without electric assistance I’d have driven.
Here in the US, we’ve built ourselves into a bunch of low-density suburbs - e-bikes represent an incredible opportunity to reduce carbon emissions now, without needing to demolish entire communities and rebuild them more densely.
